Definitions

  • the present invention relates to an electrical connector provided with a short-circuit element.
  • the invention relates to a plug-type connector, comprising a female connector element (or insert) or socket and a male connector element or plug, in which the shorting is provided of the output terminals connected to the socket contacts, for example those of the secondary winding of a measuring current transformer (a.k.a. “amperometric transformer” or CT), before the corresponding plug is fully withdrawn from the socket.
  • a measuring current transformer a.k.a. “amperometric transformer” or CT
  • Object of the invention is to eliminate the drawbacks of prior art.
  • one object of the invention is to provide an electrical plug connector that ensures the shorting of the output terminals, connected to the socket contacts, before the corresponding plug is fully withdrawn from the socket.
  • Another object of the invention is to provide such an electrical plug connector which is of simple construction and manufactured with a reduced number of components. Yet another object of the invention is to provide such an electrical connector which is of economical construction and highly reliable.
  • FIG. 1 shows a perspective view of a plug connector according to the invention, with the two elements of the plug connector, respectively socket and plug unmated and both sectioned with a vertical plane in order to highlight the internal elements of the same.
  • FIG. 2 shows the plug connector of FIG. 1 in the fully mated position.
  • FIGS. 3, 4, and 5 show in cross-section the plug connector wired and respectively unmated ( FIG. 3 ), in the initial mating position but with short-circuit element still active ( FIG. 4 ) and in the position of full mating with short-circuit element fully open by means of the plug actuator pin ( FIG. 5 ).
  • FIGS. 7 and 8 are front views respectively of the socket element and plug element of a plug connector according to the invention.
  • FIG. 9 shows in perspective the two halves, respectively socket and plug of a plug connector according to the present invention.
  • a plug connector according to the invention, globally indicated by the reference number 1 , comprises a first element or connector half socket-type 10 having an insulating body 2 provided with at least a pair of facing contacts of the female type 3 , 4 each having a front end 3 a , 4 a shaped in the manner of a bushing and a rear end 3 b , 4 b for housing a respective conductor 40 for connection to an electric circuit, and an element or connector half plug-type 20 having an insulating body 2 ′ provided with at least a corresponding pair of male contacts, 3 ′, 4 ′, each having a front end 3 ′ a , 4 ′ a shaped in the manner of a pin and a rear end 3 ′ b , 4 ′ b adapted to house a respective conductor 40 ′.
  • the female contact 3 , 4 and male contacts 3 ′, 4 ′ are provided with spring-clamp terminals 43 , 43 ′, as foreseen for example in the multipole plug connector of the patent application MI2012A 001974 in the name of the same applicant ILME S.P.A., and are adapted to lock the respective conductors 40 , 40 ′ by means of the respective actuator pins 41 , 41 ′ which, in this case, are provided with longitudinally extended opening 42 , 42 ′, for the access of the probe to a test device to allow electrical measurements.
  • the plug connector 1 can be of any other type and the locking of the conductors 40 , 40 ′ can be, for example, of the screw type, of the insulation piercing type or of the insulation displacement type, or the like.
  • a short-circuit element 5 is provided, best seen in FIGS. 3-6 , in the form of a strip of resilient conductive material with a spring function and shaped so as to offer to both its ends 5 a , 5 b an elastic contact.
  • the first end 5 a is a substantially integral contact with a respective female contact 3
  • the other end 5 b upon unmated plug connector 1 , goes intimately into contact with the other socket contact 4 of said at least one pair of contacts of the socket connector 10 .
  • an opening 11 suitably shaped is also present, adapted to receive a corresponding actuator pin 6 arranged on the mating face of the second plug connector half 20 , between the two front portions 3 ′ a and 4 ′ a of the respective pin contacts.
  • a corresponding actuator pin 6 is present, between each pair of facing male contacts 3 ′, 4 ′, integral with the insulating body of said second plug connector half 20 , having a substantially prismatic development, reproducing the T-shape of said opening 11 , and with upper end 6 ′ wedge-shaped.
  • the actuator pin 6 can be made in a single piece with the body 2 ′ of the plug connector half 20 , or be reported on it.
  • said pin 6 during mating (closing) of the two connector halves respectively socket 10 and plug 20 , said pin 6 , with a suitable delay compared with the electrical coupling between the corresponding male contacts 3 ′, 4 ′ and female contacts 3 , 4 , operates the progressive opening of the short-circuit element 5 placed between the two female contact elements 3 , 4 in the first socket half 10 of plug connector 1 (socket connector), operating a eversion of the respective spring arm and the opening of the contact between the end 5 b and the corresponding female contact 4 .
  • said actuator pin 6 made of insulating material, restores, upon plug connector half 20 mated to the corresponding socket connector half 10 , the necessary electrical insulation between the two facing parts of female contact 3 , 4 .
  • Coding pins 13 are also visible in the appended figures, normally colour-coded, mounted in corresponding seats 12 for a correct coupling of the connectors.
